The ink is delivered from the puA outlet 13 and passes upward diront. manifold 16 and into inl: container ink container, which he any closed conduit, is provided nth an e r ci ber 18 to secure a 1ere uniorin upon the ink, and a reni t 'ik 19 is a plied. A relief valve i4 pump outlet has a discharge pipe 217 back into tank 10. In operation, the pin'np is driven continuouslyT and causes a constant quantity of ink to he deli/'ered at ou?" This supply is enongi to keep the coi: 17 filled with ink under pressure, and the excess passes th relic-1." valve 14 and pipe 20 back into mii 10,

l'n order to c e feeding of ink from the conta;y Aable valve mechanism is provid z be of any suitable form to seM A regular but an interinl. A form of valve YFarnese is shown in Fig. 3 i valve casing 21 suitably attached to t inkcontainer 17 and provided with de ery tubes v22 which abut the periphery of distributing roll 23and which communica with a duct 24 leading into the container The valve is indicated at 25 and is rsided with a port 26 which permits of ink under pressure from the oon- 17 to the delivery tubes 22, as the 'fe is actuated. The valve is reciprocated from e cani shaft 27, equipped with u cam 28 which contacts with a roller 29 carried by the lower end of the valve, forcing the valve upward against the pressure of 'e spring 30 surrounding a reduced portion ofthe valve as shown in the figure. The valve is further provided with a pin 32 which slides in a hey way 33 out in the valve casing 21 so that the `alve is held in fixed angular position.

vBy the mechanism thus described, it siii be noted that when the press is opera the ink will be delivered under4 in intermittent jets upon the .distrihuting roll. As" shown in Figs. 2 and there are a series of valves similar-to the one described,

adapted for thi and comprises Shaft 27, the respective cams being disposed about the shaft so as to render the load upon In the noted that the load upon the earn shaft is relatively-` light, as the work of moving thev ink is performed by the pump 1 1. y-

Means are further provided for individual As shown in Figs. 3 and 4;, the valve casing 21 is equipped with a cap 35 which serves 'as an abutment for spring 30 and terminates in a threaded end 36. A nut 37 is mounted upon the threaded endA 36, the rotation of the nut-serving to move it in a vertical direction. The upper end of the valve 25 is pio-vided with a tappet head 33 adapted to contact with the nut 37. The nut limits the downward movement of the valve, operating as a stop, and it is obvious that if the nut be adjusted to .an extreme upper position, it will hold the. valve in its closed position, shutting ofi" the ink completely; likewise if the. nut be lowered, the valve .25 will move downward, whenever permitted by the cam,

7 so that the iort 26 is more o!- less uncovered,

according to the adjustment of the nut. In this way the extent of movement of the valve, and the ink feed, are controlled by the adjustment of nut 37.

To facilitate the adjustment of nut 37, the following mechanism is provided. As shown in Figs. 3 and 5, the ink container 17 is fitted with brackets L'l0 equipped with a yoke .4.1 supporting a bushing 42, the bushing being equipped with a spiral gear 43 and being adapted to rotate upon the yoke. The bushing has a spline and feather' connection with the nut 37 as indicated at 44 so that rotation of the bushing will rotate the nut, but only the nut has a resultant vertical movement. The bracket 40 carries a bearing 45 in which is located a shaft 46 equipped with a spiral gear Lt7 meshing with gear 43. As shown in Fig. 2, the shaft 46 ext-ends to one or the other side of the press where it is supported in a suitable bearing and terminates in a wrench head through which it may be rotated by a suitable wrench as indicated at 48.

Figs. 6 to 11 inclusive illustrato a moditied form of mechanism securing the same results.

AS shown in Fig. 6, the valve casing 5() is attached to the ink container 51 and abuts the distributing roll 52. A duct 53 leads from the container to the outer surface of the casing 50. Intercepting the duct is a valve 54, adapted to reciprocate in the cas ing 50, provided with a spur gear 55, and coupled to an eccentric strap 56 by a ball and socket joint 57. The strap 56 surrounds an eccentric 58 pinned to shaft 59. The shaft 59. being continuously driven, reciprocates the valve with a uniform extent of throw. The regulation of the ink supply is secured by an angular movement-of the valve, as illustrated in Figs. 8, 9 and 10.

To rotate the valve a rack 60 is provided which meshes with spur gear 55. The raclr is pinned to a rod 61 adapted to slide in a suitable bearing.62 but prevented from ro? ta-ting therein. A stub shaft 63 engages a threaded recess in the rod 61 and is rotatably mounted in the frame 64 of the press, and is further equipped with a wrench end 65. As is obvious, rotation of the shaft 63 will cause a longitudinal movement of the -rod 61 and rack 60, causing an angular movement of the valvewhich will determine the extent of opening of the port 66. As shown in Fig. 6, the gear 55 is of greater width than the rack 60, so that the valve and gear 55 may reciprocate without getting out of mesh with the. rack, which has no lateral movement.

As in the former embodiment of the in- ,vention, the ink is maintained under pressure and is driven through the ductas the part 54 reciprocates.
